6 4. Introduction Sky Scanner MS-321LR is designed to measure luminance and radiance using sensor with 11 degree aperture angle and dual-axis control driving part by dividing the sky hemisphere into 145 points Main Functions 1. Sky Scanner MS-321LR tracks the sky hemisphere by dividing it into 145 points, measuring luminance and radiance in 4.5 minutes using the sensor with 11 degree aperture angle and dual-axis control driving part. The measurements of 145 points are based on the CIE recommendation. (CIE - International Lighting Commission, IDMP - International Daylight Measurement Programme) Sensors are calibrated before shipment. Luminance value can be measured in kcd/m 2 and radiance value in W/m 2 sr for their units. 2. Software The software specially programmed for the MS-321LR displays the luminance and radiance values in color and text. Moreover by setting the latitude and longitude of the measurement location prior to the measurement, the sun position (the sun elevation and azimuth) is calculated, displayed, and saved in the data..

10 5-3. Installation 1. Preparation 1) Installation Location & Setup Conditions Install the Sky Scanner in a place where nothing obstructs the view of the sensors. The ideal mounting position for Sky Scanner is a location which has a free field-of-view without any obstructions (such as buildings, trees, and mountain). In practice, it might be difficult to find such locations; therefore, some practical recommendations on how to minimize undesired effects of reflecting or obstructing surfaces are given next: Select a mounting position which it is free from obstructions at 5 above horizon. The setup location should be easily accessible for periodic maintenance (Sensor cleaning, check for level and cable condition, etc.) of the Sky Scanner and mounted instrument(s). Avoid to place the Sky Scanner in the area of surrounding objects e.g. towers, poles, walls or billboards with bright colors that can reflect solar radiation onto the pyranometer. 2) Checking the Orientation Sky Scanner must be installed orientated in North / South direction. By determining the direction of north/south, prepare the setup base as instructed in the next step [3) Preparation of Setup Base]. How to determine the True-North/South: True-North/South is a direction to the North/South Pole of the Earth. The North/South pointed by magnetic needle of a compass is called magnetic north/south. Magnetic north/south has a few degrees to more than ten degrees of deviation from True-North/South. Since this deviation differs by areas, it is recommended to check the deviation of magnetic north/south at your measurement site in advance. When installing the Sky Scanner, search for True-North/South by correcting the deviation of magnetic north/south. There are following other methods to setup the Sky Scanner in the True North-South line: (1) Using a geographical Map (such as Google Map): By referencing a mountain, a building, or a tower which can be seen in far location from the installation site, figure out the direction of the object from the site on an accurate terrain map, the accurate north/south direction can be determined by using protractor. (2) Determine the south from the sun position at culmination time. The time Sun passes the true south (culmination time) can be determined from a scientific chronological table. Culmination time is also provided on local astronomical observatory website. Accurate south direction can also be determined by shadow of perpendicularly positioned stick and string with weight. EKO INSTRUMENTS CO., LTD. Sky Scanner MS-321LR Instruction Manual V5 Pg. 9

11 3) Preparing Installation Base Prepare a setup base with fixing holes for the anchor bolts (M8) as shown below. Orientation of the installation position will be important, thus carefully check the position of the anchor bolts. Make sure that the mounting base can hold total weight of the Sky Scanner itself and the sensors mounted on the Sky Scanner. The anchor bolts must be attached to hold the Sky Scanner on the setup base. To avoid unexpected accidents or damage due to strong wind or gale, make sure to fasten the tripod on the stage or ground securely. Figure 5-3. Anchor bolt position 2. Installation Procedure 1) Put Sky Scanner on the installation base in the right direction. You must direct the base with a level should to True-North (True-South when installing the Sky Scanner in Southern Hemisphere). True-North (true-south) is a direction to the North Pole (South Pole) from the measurement site. The North (South) pointed by magnetic needle of compass is called magnetic north (magnetic south). Magnetic north (south) has a deviation of from several to ten degrees from True-north (true-south). This deviation vary by each area, the deviation of magnetic north (magnetic south) should be checked for your measurement site in advance. When installing Sky Scanner, search for true-north (true-south) by compensating the deviation of magnetic north (magnetic south). There are other methods to determine the true north (true south), such as using a precise topographic map and point of target and sun position at the time of solar noon time. When the Sky Scanner is powered ON, the Driving Part will point to South (North). Then adjust the true-north (true-south) direction of the Driving Part as mentioned above. The Sky Scanner determines the azimuth angle references the tripod base with spirit level as the true north (true south), Azimuth angles are defined by true south (true north) as 0 ( zero degree), clockwise rotation as positive and anti-clockwise rotation as negative (-180 to +180 ), and these definitions are also used in the software. EKO INSTRUMENTS CO., LTD. Sky Scanner MS-321LR Instruction Manual V5 Pg. 10

12 2) Adjust the leveling screws to setup the tripod in horizontal position. Use the leveling screws to bring the air bubble inside the spirit level in the center of the circle indicated. 3) Once the position and horizontal level for the Sky Scanner has been completed, fix the Sky Scanner securely onto the mounting base using attached M8 bolts. 4) Attach the optical sensor on the mounting plate. After placing the optical sensor on the V-block attached on the mounting plate, secure the optical sensor with attached fixing rings. 5) Install personal computer in a safe and suitable area.

13 5-4. Cable Connections 1. Output Cable Connection Connect the connectors on the sensor side and Driving Part side with provided signal cable. Make sure the cables are routed with sufficient length for Sky Scanner movement to prevent cable from getting caught or tangled on the leveling screws, etc. First place the signal cable on the Driving Part axis then connect the cable ends to each connectors. Make sure the signal cable will not get caught on the leveling screws when the Driving Part turns. Figure 5-4. Signal Cable Position 2. Communication Cable Connection Connect the Sky Scanner and the PC RS232C connector with provided communication cable. Make sure the cables are routed with sufficient length for Sky Scanner movement to prevent cable from getting caught or tangled on the leveling screws, etc. 3. Power Cable Connection Connect between the power connector and AC power supply with the power cable. Make sure the cables are routed with sufficient length for Sky Scanner movement to prevent cable from getting caught or tangled on the leveling screws, etc. Run the power cable and communication cable twice around the tripod with sufficient length as shown on the left. Figure 5-5. Power Cable and Communication Cable EKO INSTRUMENTS CO., LTD. Sky Scanner MS-321LR Instruction Manual V5 Pg. 12

14 4. Extension Cable Connection (Optional) For the connection with the optional communication cable longer than 20m, connect RS422/RS232C exchanger as shown in the following Fig.3. Standard communication cable is RS232C, but the extended communication cable is RS422. In this case, RS422/RS232C exchanger is necessary.
